When you start a conversation or give a speech, you might want to introduce
your topic or yourself. Saying “By way of introduction” is one way to do
this. It's a formal phrase that means you're starting with some background
information. This expression is correct and appropriate in professional or
formal settings. However, in casual talks, simpler words like “to start” or
“beginning with” are more common and easier to understand. So, while “By
way of introduction” is not wrong, think about who you're talking to and
choose your words to match the situation.
